However, a few keens eyes have found the ring actually appeared on Kate's finger, long before Prince Louis's birth.

In fact, so long before his birth the Duke and Duchess of Cambridge weren't even married yet.

Kate was seen heading back home with sister Pippa Middleton after celebrating her birthday in January 2008.

However, the ring is not as new as it seems with keen Royal watchers spotting it on Kate's hand back in 2008 (Getty)Kate was seen wearing it on her birthday in January 2008, followed by a friend's wedding in July 2008 - before she and Prince William were even married (Getty)

In July the same year, it was seen again on Kate's hand as she attended the wedding of Lady Rose Windsor and George Gilman.

So if it was a present from her Prince, it was one William gave her while they were dating (almost makes it a more impressive gift!)

With "push presents" said to be a Royal Family tradition, The Duke of Cambridge reportedly gave the Duchess a pendant on the birth of their first child, Prince George, in 2013.

It's understood the circular pendant is inscribed with their newborn heir-to-the-throne's full name on it.

While after Princess Charlotte's birth in 2015, it's understood Kate was gifted a pair of tourmaline, green amethyst and diamond earrings.

They were created by one of the Duchess's favourite jewellers - reportedly costing almost $5,500 - and were seen for the first time when the Royal couple were on an official tour of India and Bhutan in 2016.
